Here is a cool thing…

Some of the green wall panels at the VISIONA 2 exhibition 1970 were not only panels – they were lamps!

If you look at the pictures above you can see that the colours are a bit different for the ones to the left compared to the others.

The big “bumbs” are lit up as you you also can see on the picture shot from a distance.

This “new” info gave me an idea regarding a prototype panel I have… I will soon show you what I think.
